Let's talk antibodies

So here is my H pylori antibody test results.
See image/attachment
My understanding is
IgG = chronic infection
IgM = acute infection
IgA= ?? Severe inflammation per labcorps guideline?
See below, From labcorps test menu website.
"Additional Information
Circulating antibodies to H pylori are predominantly of the IgG class. A systemic response of the IgA type is usually less pronounced but, if significant, may indicate a more severe inflammation. A few patients develop only antibodies to IgA. IgM antibodies are rarely found and appear to be of minor importance."
2nd question.
If I eradicated h pylori, I'll retest in 3 weeks. Should I expect my current IgG level go down if I was to check my IgG antibody like in 3 months, or will it sit at around my current level for months even after eradication?
